Acoustic fences for roads

GRAMM SmogStop - the world's first approved air quality barrier - reduces air and noise pollution levels in surrounding neighbourhoods, and takes a two-pronged approach to reducing air pollution from major roads, highways and railways. The patented aerodynamic design reduces pollution levels by enhancing dispersion so that neighbouring residents

WHIS®top is a lightweight aluminium diffractor that can be mounted onto any existing noise barrier to deflect sound upwards. It adds a 4-5 dB noise reduction, comparable to raising the existing barrier 2m. Improves reduction from existing noise barriers without radical measures. Any new noise barrier can be lowered by 2m with WHIS®top

Greenscreen is an environmentally-acceptable flexible and natural noise barrier and, using technology developed in the professional growing industry, it is designed to support climbing plants. Over time the screens become completely clothed in foliage, creating a natural 'greenscreen' barrier. The barrier's pleasant aesthetic blends in with any

NATURALSoundBlok Reflective acoustic fence by Gramm Barrier Systems is a timber noise barrier system designed for high sound reduction in rural settings. Made from pressure-treated, FSC-certified timber, it uses a double acoustic board design to maintain an acoustic seal throughout its 30-year maintenance-free lifespan. Heights and bay widths are

GRAMM CONCRETESoundBlok® noise barriers are made of a proprietary material consisting of organic softwood shavings processed to an acoustically engineered size and bonded together under pressure with Portland cement.

TILESoundBlok® noise barrier tiles are manufactured from carefully selected specialist aggregates with angular face which are bonded together using the company's patented method. This allows the system to use a low amount of binder while still retaining a strong bond, resulting in a robust material ideal for sound absorption in a variety of

The Hatko NB3 Absorptive recycled rubber tyre noise barrier, supplied by Gramm Barrier Systems, is a high-density acoustic panel system manufactured from end-of-life recycled rubber tyres and sound -absorbing recycled plastic. Designed to reduce road, rail and industrial noise, Hatko supports Net Zero and circular economy objectives while

Transparent noise barriers make an effective yet aesthetic contribution towards reducing sound emission. The CLEARSoundBlok® ABSORPTIVE barrier considerably reduces the noise level in the area behind the wall. This unique barrier design offers all the benefits of a clear system whilst also offering an absorptive surface which is critical in

GREENSoundBlok® is an innovative acoustic barrier based on an aluminium sectional frame for increased stability, with reinforced vertical bars for even higher noise barriers. It offers excellent sound-insulating and highly absorptive performance, classified in B3 and A3-4 on both sides. Tongue-and-groove interlock for easy stacking of multiple

GRAMM Green noise barrier is a mineral wool-based noise barrier, which offers good absorption and insulation values. The barrier panels consist of metal mesh covered with a PE net. The PE net can be supplied in different colours. All galvanised steel material can be powder coated, on request. The steel net has a rectangular mesh pattern so that

Gramm Barriers ECOSoundBlok® is a green noise barrier system made from steel, acoustic matting, and soil fill, designed to reduce noise pollution while supporting plant growth and carbon reduction. Suitable for heights from 0.5m to 6m+ and bay widths from 10m. Maintenance-free for 30 years and does not require concrete foundations: green noise

METASoundBlok® is a metal noise barrier system made from galvanised steel with sound-absorbing mineral wool, designed to reduce noise from road and rail traffic. Panels are lightweight, removable and fully CE compliant, with a perforated inner face for absorption and a plain outer face for reflection. Heights and lengths are customisable for

CLADSoundBlok® panels from Gramm Barriers are made from upcycled polymer blends called PC-ABS (Polycarbonate-Acrylonitrile-Butadiene-Styrene). The innovative and surprisingly strong pyramidal shape (500 x 500mm) allows contractors to create an aesthetically-pleasing sound absorber on almost any wall or ceiling. Low-carbon panel with high UV resistance

Aluminium Louvred Acoustic Barriers have been uniquely designed to provide high levels of sound reduction while allowing air to flow through. They can be installed in any location with either concrete-in or base-plated posts. Sound reductions of up to 30db are provided. Applications include: generator compounds; chiller compounds; data centres; air conditioning

Jakoustic® timber or galvanised steel framed acoustic gates are configured as singles or pairs to BS EN 1461. Jakoustic® Reflective and Jakoustic® Absorptive types. Swing and tracked sliding designs. Manual or automated operation. Swing gates up to 2.5m wide per leaf; 2.5m high as standard. Tracked sliding gate leaf sizes up to 13.0m wide and 4.0m high

POLYSoundBlok® recycled PVC environmental noise barrier systems are manufactured entirely from high-strength reinforced PVC, negating the inherent issues that come from using timber. POLYSoundBlok is a highly durable rigid panel that will not warp or shrink, is rot-proof and resistant to aggresive environments and compounds such as salt spray and

Vehicle restraint systems and noise barrier walls normally are considered separately. Therefore, more space is required and the efficiency of noise reduction is reduced. Gramm Barriers combines those two systems to one CE-certified solution, the COMBISoundBlok® series. The COMBISoundBlok® integrated noise barrier is designed as a free-standing

WHIS®stone is a concrete noise defractor designed for quick and easy installation at roadsides. Sitting at the same height as the ground surface and taking up on 1m of road space, WHIS®stone will reduce traffic noise by 2.5dB, or up to 4dB when using a double row. The concrete elements are safe to drive over and have a drainage system installed

Greenscreen modular noise barriers have a high noise insulation value of 30dB Rw and a high sound absorption level of up to 10dB. Durable coconut fibres make it suitable for supporting climbing plants, as well as acoustic insulation. Within a few years, the greenscreen barriers will be completely covered with plants. Made from galvanised steel

WHIS®wall combines a low noise barrier with a weathering steel diffractor. It is 1m-high, leaving the view intact for residents, drivers and rail passengers.
